all whom it may concern: nector which is adapted to connect together Be it known that I, THEODORE A. WILLARD plate of opposite olarity of adjoining cells,

a citizen of the United States, residing at and the other, which is shown at the left East Cleveland, in the county of Cuyahoga hand side of Fig. 1, being an end or terand State of Ohio, have invented a certain minal conductor to which a flexible conductor new and useful Improvement in Storage Bat- 1s adapted to be connected.

The sealing means consists of applicatlon, thus intimately or integrally sleeves,'which as shown in said application, unitlng the terminal posts, connectors and are at their lower ends embedded ormolded' sealing sleeves. This lead-burning, as fully 20 in the cover around the posts and extend described in my prior application, is acupwardly along the latter, and at their upcomplished 1n the following manner: The per ends are interposed between the posts connectors have sockets which are preferably and connectors and are lead-burned to both tapered in opposite directions from the the latter. center as shown particularly. at the left hand 25 In the present invention, similar sealing side of Flg. 1, and the upper ends of the sleeves are employed, one of the features of posts and the sealing sleeves have conical the present invention being a novel manner portions WhlCh extend into the lower tapered of connecting the lower ends of the sleeves parts of the sockets.

This is accomplished to cation. in this case by embedding the .lower portions '95 Referring now to the drawings, 10 repreof the sleeves in soft rubber inserts 16, which sents the jar or container, and 11 the cover, are seated in depressions of the cover imwhich i referably of rubber and one of 'mediately surrounding the posts and are which wilibe provided for each cell of'the vulcanized to the cover. This forms a cover,

at batte Each ell of the battery will be the main part of which isof hard rubber provi ed with the usual positive and he awith the portions immediately surrounding tive plates having the positive and negative thev openings for the terminal posts of soft terminal posts 12 whlch extend upwardly rubber. This cover is formed by using rubthrough the cover 11. A vent plug is usually ber for the main part thereof containing at screwed into an opening 13 in the cover, but the usual amount of sulfur to form hard the plug is not here shown as it forms no rubber dur ng vulcanization and by placing part of the present inventlon. At the upper in the depressions around the terminal post ends of the post 'are connectors 14 havmg openings rubber inserts containing no sulsockets which recelve the upper ends of the fur. In the subsequent vulcanizin process 55 posts, one of the connectors beingacross conenough sulfur will pass from th t rubber 0 forming the main part of the cover to the inserts16 to effectively vulcanize these parts to ether.

In my prior application the sealing sleeves are vulcanized in the hard rubber cover, and

- forms, some of which I have illustrated in Figs. 2 to 4. The sealing sleeve of Fig. 2, designated 15, has a lower -c0rru ated flange. The sealing sleeve of Fig. 3,. esignated 15", has a perforated flange through which the rubber will extend, and the sealing sleeveof Fig. 4, designated 15, has an open slotted flange, these constructions all resulting in good unions between the lead sealing sleeves and therubber-which receives them.

It is sometimes desirable that the sealing sleeve be not lead-burned to the connector and that the latter be clamped about the same, this being particularly true with respect to the terminal connectors of certain batteries. This isillustrated in Fig. 5,

wherein the terminal post 12* is of cylindrical form throughout, and the sealing.

sleeve designated 15", has-its upper sleevelike portion likewise cylindrical, the latter engaging and being lead-burned to the post, the lower end of the sleeve being embedded in the softirubber cover insert 16, as in the construction of Fig. 1'. The terminal'connector which is here designated 14, is clamped about the upper portion of the -sealing sleeve, and, the upper end of the latter where it is united to the post by leadburning, is peenedi over the clam In these batteries having their two terminal or end connectors simply clamped to, the sealing sleeves and posts, the cross connectors are preferably lead burned to both the sealing sleeves and posts, as in Fig. 1.

Having described my invention, what I claim is:-- Y

1. In a storage battery, a container having the cover, a sealing sleeve surrounding the post and having its lower end flexibly but tightly connected to the cover, and its upper portion lead-burned to the post.

2. In a storage battery, a container having a cover, a terminal post extending through the cover, a connector receiving the upper end of the post, a sealing sleeve surrounding the post, said sleeve having its lower portion flexibly but tightly connected to the cover and its upper portion interposed between the post and the connector.

3. In a storage battery, a container having a cover, a terminal post extending through the cover, a connector receiving the upper end of the post, a sealing sleeve surrounding the 0st, said sleeve having its lower portion flexl 1y but tightly connected to the cover and its upper portion interposed between the post and the connector and lead-burned to both the latter.

4. In a storage battery, a container having a cover with a yieldable insert secured thereto, a terminal post extending through the insert of the cover, and a sealing sleeve embedded in said insert and extending above the cover and secured to the post.

5. In a storage battery, a container having a hard rubber cover, a soft rubber insert vulcanized thereto, a terminal post extending through said insert, a sealing sleeve having its lower portion embedded in the insert, a connector at the upper end of the post, said sealing sleeve being lead-burned to the post or to the post and connector.

6. In a storage battery, a container having a cover, an insert vulcanized thereto, a terminal post extending through the insert, a

connector engaging the upper part of the post, and a sealing-sleeve molded in the insert around the post and integrally secured to the connector.

7. .In a storage battery, a container having a hard. rubber cover, an insert vulcanized thereto, a terminal post extending through said insert, a connector attached to the post,

and a sealing sleeve havingits lower portion molded in the insert around the post and having its upper portion integrally secured to the post or connector or both.

In testimony whereof, I hereunto aflix my signature.
